Description
A 2 Channel DIY Oscilloscope based on STM32F4x1 Black Pill development board. It provide long memory buffer and high real-time transfer speed. As the HS10X series it keep the best ratio performance/cost/ease to build. Power consumption is also one of the lowest in the market (~40mA). It can be used only with [HScope app](https://play.google.com/store/apps/details?id=com.martinloren.hscope) for Android. **Other** [Official project page](https://www.martinloren.com/hs40x-diy-oscilloscopes/) **Disclaimer** This is an old version of the PCB board. Please check on [Github](https://github.com/martinloren/HScope/tree/master/HS402) the latest v2.0 or v3.0.
